The treatment plant is located on Bruton Craft Lane in Pinetops, North Carolina, in Edgecombe County. The design capacity of the treatment system is 0.3 MGD. The facility maintains one outfall, which discharges into Town Creek, classified Class C-NSW waters in the Tar -Pamlico River Basin. Town Creek is not listed as impaired on the 2010 303d list. DMR Data Review DMR data from January 2008 through December 2010 were reviewed. These data are summarized in Table 1.

NC0020435 DMR Data (January 2008-December 2010) TOXICITY TESTING Current Requirement: No Toxicity Testing Recommended Requirement: No Toxicity Testing Fact Sheet NPDES Renewal NC0020435 Page 1 INSTREAM MONITORING Instream monitoring is done for temperature and dissolved oxygen. The downstream DO levels (monthly averages) were higher than upstream 84% of the time. Upstream DO samples were less than 5.0 mg/ L 88% of the time, while downstream DO samples were less than 5.0 mg/ L 66% of the time. So the facility discharge is generally having a positive impact on the stream. Effluent D.O. had a minimum value of 5.8, so the effluent never violated the D.O. standard of 5.0 mg/ L. COMPLIANCE SUMMARY BIMS (2008-2010) indicate that the facility received one NOV during the time frame. The NOV, issued 1/27/2011 for two monitoring frequency violations for Total Suspended Solids and Fecal Coliform, both in October, 2010. Compliance Evaluation Inspections noted no serious problems in the operation and maintenance of the facility. Excessive Inflow and Infiltration continues to be a problem. The plant is working on correcting this situation, and is seeking funding for I/I rehabilitation projects. BOD/ TSS REMOVAL RATE The facility is well within the 85% removal requirement for BOD and TSS. BOD removal rate is 98.3%, and TSS removal rate is 98.7%. Reasonable Potential Analysis (RPA) No RPA was conducted, as there are no parameters monitored that would warrant an RPA. Pinetops is a minor facility treating 100% Domestic waste. Special Condition A.(2) Wastewater Management Plan The previous permit had a special condition A.(3) Wastewater Management Plan which required a wastewater management plan be developed and submitted to the Division. The plan includes two parts, a facility assessment describing deficiencies and operational difficulties in the existing facility and how to correct them, plus a study of inflow and infiltration in the collections system. The second element is a biosolids management plan. The facility did not do either of these items, so was not in compliance with the permit. These studies have been retained in the renewal draft, renumbered as A.(2). Raleigh Regional Office will likely fine the Town for noncompliance with these permit requirements. PROPOSED CHANGES In keeping with Division practice, the following will be incorporated into the permit: • The equipment listing on the Supplement to Cover Page was revised to include dechlorination and an automatic starting back up generator. • "Total Suspended Residue" was changed to "Total Suspended Solids" in accordance with current practice on page A.(1.). • Format changes were made to A.(1.) in compliance with the WQ basin plan. The DO and pH values were moved up into the table and the footnotes removed. • The TRC footnote was updated in accordance with our current TRC permitting strategy regarding reported values less than 50 µg/ L being considered to be in compliance with the permit. • Tar -Pamlico Basin Association information regarding Nutrient Reduction was added to the permit as Special Condition A.(3.).

The waste stream then enters the bar screen and grit removal structure.There is provision for PH control at this point. Waste then enters the aeration basin for further treatment. The detention time in the aeration basin is approximately thirty hours. Waste then enters the secondary clarifier for solids removal . Sludge from the clarifier is recirculated to aeration basin or wasted to the aerobic digester. Effluent enters chlorine contact chamber then to post aeration and dechlorination then to plant outfall 001. Dried sludge is disposed of at the Bertie County Landfill. Plant additions Effluent from the plant is now being Dechlorinated before discharge also a water reuse system has been installed for wash downs at plant There is no connection to potable supply. The plant now has an auto start generator capable of supplying power to all plant processes. Phil o.
